A Multi-level Dynamic Database Model of Geological Disaster Emergency Remote Sensing Monitoring

Abstract

A quick obtainability of pre-disaster data like remote sensing and geology data of the disaster area is big trouble in emergency rescue. Therefore a flexible and complete database that can easily and quickly extract pre-disaster background data of the disaster area is very important. A Multi-level Dynamic Database Model of geological disaster emergency remote sensing monitoring was put forward in this paper. And the concept of form and physical storage structure was elaborated in detail. Through a test of landslide disaster in Shuicheng in Guizhou province and Zhouqu in Gansu province, the model shows good applicability for different kinds of geological disasters and different areas.
